How can I protect my family my grandmas moocher husband is trying to put her in a home because she’s sick and doesn’t want to take care of her.
Protect your family? In what way is anyone in your family (with the possible exception of your grandmother) in need of protection?
Regardless of how you answer that, the only possible things you can do about your grandmother's situation are (1) contact elder abuse authorities in your grandmother's county of residence, and (2) seek to establish a conseravorship over your grandmother. If you want to go with option #2, you'll need to consult with an attorney.
Out of curiosity, if your grandmother agrees with you, why doesn't she hire an attorney to file for divorce and seek a restraining order to get her husband out of the house? Is the house in her name only or both of their names jointly?
My mom pushed his shoulder the other day because we are all honestly so tired of him and he called police playing the victim.
Well...what you described is assault/battery, and he was the victim. So what's the problem with this?
Can we make her sign something that she does not want to be in a home?
You want to "make" (i.e., force) her to sign something? Isn't that charming? You can
ask her to sign anything you like, but the decision to do so or not to do so is entirely hers.
can we record her telling us that can we take her to get a poa.
No one here has the slightest idea what abilities you have.
I’ve taken my grandma to the police station I’ve called social services so many times.
And they've done nothing? If that's the case, then maybe there's nothing to be done here and your allegations to the contrary don't withstand scrutiny. I make this point because we are all complete strangers to the situation. We don't know who's right and who's wrong. Just because you've made allegations doesn't mean we must blindly assume them to be true. When you add that objective authorities are doing nothing in response to your allegations, that strongly suggests that things are not as bad as you allege.
